Calorimetry-the science or act of measuring changes in state variables of a body for the purpose of deriving heat transfer associated with changes of its due date.
A binary compound is a compound formed from two different elements. There may or may not be more than one of each element. A diatomic compound (or diatomic molecule) contains two atoms, which may or may not be the same.

Nomenclature of Ionic and Covalent Compounds.
The water of hydration is not covalently bound to the compound.
Many compounds, especially ionic compounds contain molecules of water of hydration which appears as part of the chemical formula of the compound.
This water of hydration is only attached to the crystal of the compound loosely. There is no chemical interaction between the water molecules and the crystal of the compound.
To prove this, the water of hydration is easily driven off by heating. It wouldn't have been possible to drive it off by heating if was covalently bonded to the compound.
Therefore, the water of hydration is not covalently bound to the compound.
